Photoshop actions with GIMP#

I have been playing with the thought of support for Photoshop actions in GIMP#. There are however several hurdles:

Adobe stopt documenting their fileformats after Photoshop 6.0. The good news is that since then the format of the action files hasn't changed (much). The bad thing is that lots of new functions have been introduced. This will require some serious reengineering.

It's not always a one on one mapping of functionality. Filters like "Gaussian blur" are available in both Photoshop and GIMP. There are however lots of other filters that don't have an equivalent. When we are lucky we might be able to map some filters to one or more other filters. For example the GIMPressionist plug-in might be able to emulate several Photoshop plug-ins.

Even if the plug-ins are similar, there might for example be a difference in the range of the parameters.

Probaby more to come…

So in theory this should be possible for a subset of all Photoshop actions. This would add a lot of cool stuff to GIMP and it would certainly help to make the transition from Photoshop to GIMP even easier.
